TD3112
General Description 
Features   
The TD3112 is a 380 KHz fixed frequency monolithic
step down switch mode regulator with a built in internal
Power MOSFET. It achieves 2.2A continuous output
current over a wide input supply range with excellent
load and line regulation.
The device includes a voltage reference, oscillation
circuit, error amplifier, internal PMOS and etc.
The PWM control circuit is able to adjust the duty ratio
linearly from 0 to 100%. An enable function, an over
current protection function and a short circuit protection
function are built inside. An internal compensation block
is built in to minimize external component count.
